Remanufactured / Exchange Option

We have created a specialized DPF cleaning remanufacturing process, specifically tailored for your diesel truck or equipment needs. Don’t let engine “limp” modes destroy your wallet. A clogged filter can split or warp over time, and it will need to be replaced with a new one that cost thousand of dollars. Not to mention all poor fuel mileage bills.
